SIDE SPRING FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 312,174, dated February10, 1885.

Application filed October 25, 1884. (No model.) I

To all whom, it may concern:

Be it known that I, JAMES H. SNODGRASS, a citizen of the United States,residing at Miffiinburg, in the county of Union and State ofPennsylvania, have invented a new and useful Improvement in SideSprings, of which the following is a specification, reference being hadto the accompanying drawings.

This invention relates to side-spring vehicles, and more particularly toan improved coupling orjoint for connecting the ends of the side springsto the front and back springs; and it has for its object to provideadevice of this character in which the attachment will be strengthenedand made superior in every respect, allowing the springs to yield whilein use, and work together with readiness and ease, and yet prevent unduestrain in any direction.

WVith these ends in view the said invention consists in certain detailsof construction and combination of parts, as hereinafter set forth, andparticularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective View of aportion of the gear of a side-spring vehicle with my improvedooupling-joint for connecting the ends of the side springs to the frontand back springs. Fig. 2 is a detached view of a portion of the side andback springs, showing the parts enlarged to bring out the coupling .moreclearly. Fig. 3 is asimilar view, showingthe parts separated.

Like letters are used to indicate corresponding parts in the severalfigures. Referring to the drawings, A B designate the front and backsprings, of the usual construction, having their extreme ends providedwith upwardly-projecting lugs O G, the front and rear faces of which arecurved inward, or cut out at the base, to provide enlargedcylindrical-shaped heads for the lugs, said heads being perforatedtransversely, as at a.

D D designate the side springs, of the ordinary construction, havingtheir opposite ends passing beneath, around, and overthe front and backsprings, substantially in the form of the letter C. .The extreme ends ofthe side springs are provided on opposite sides with circular disks b b,a portion of the body of the spring being out out between the disks at eto provide room for the lugs O C. These disks 1) havealignedperforations d,to register with the perforations a in the lugs O,to receive a headed bolt, E, to the end of which is fitted a nut,F,which binds against one of the disks and makes the attachment securein every respect.

The operation of my invention will be readily understood from theforegoing description, taken in connection with the annexed drawings.TheC-shaped ends of the side springs are carried around and over thefront and back springs, the extreme ends being coupled together bypassing the bolts through the perforations of the disks 1) and the lugs0. As seen, the disks are arranged on opposite sides of the said lugs O,and held against the same, so that the front and back springs will bepermitted to yield downward, but will be braced from lateral motion. Inthe present manner of coupling the side springs to the front and backsprings by the use of shackles or knucklejoints there is too much strainon certain parts. In my construction both the side and end springsmutually support each other and have equal strain placed upon them,whilethe end springs will be held from moving laterally independent of theside springs. In this manner the action of the springs is made mucheasier, since they willmove in unison, and thus co-operate to provide alight and efficient spring.- There can be no wrenching or undue strainupon either the end or side springs, while the parts can be detached ina very short time.

My spring is specially adapted for light vehicles-such as are used byphysicians and the like-and will provide a light, strong, and simpledevice, which will prove of great utility for the purposes intended.

Having described my invention, I claim- 1. The combination, with the endsprings provided with an upwardly-projecting perforated lug at each end,of the side springs provided with C-extensions at the ends,which passunderneath, around, and over the end springs, the ends of the extensionshaving perforated disks, and bolts and nuts for coupling the disks tothe lugs, as and for the purpose set forth.

2. As an improvement in side springs, the

with upwardl y-proj ectin g lugs at the ends, the

combination, with the end springs provided heads of said lugs beingcylindrical in form,of the side springs having their ends passing aroundand over the end springs, disks on opposite sides of the ends of theside springs, a portion of the latter being cut out between the disks,and a bolt for connecting each pair of disks to the lugs, as and for thepurpose set forth.

3. As an improvement in side springs, the combination,with the endsprings having perforated lugs at each end, of the side springs arrangedbelow and having their ends passing underneath,aronnd,and over the endsprings, and bolts for connecting the ends of the side springs to thelugs, as and for the purpose set forth.
